IMPROVEMENT IN HEMP-BRAKES.

Specification forming-part of Letters, Patent No. 23,9416, dated May 10, 1859.

To all whom it may concern.-

Be it known that I, J. -W. RlNEliART, of Lexington city, in the county of Lafayette and State of Missouri, have invented a new and Improved Hemp-Brake; and I do hereby 1 declare that the following is a full, clear, and

exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is a side sectional view of my invention; Fig. 2, a plan or top view of the same.

Similar letters of reference indicate corre sponding parts in the two figures.

This invention consists in a peculiar manner of operating a swinging or oscillating beater-frame, which is used in connection with in proper, bearings, c, on the frame A.

shaft a extends the whole width of the frame stationary beatcrs, as hereinafter fully shown I and described, whereby the woody portion of the hemp may be broken and detached from fiber in a very expeditious and perfect manner.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A represents a frame, which may be of rectangular form and of any proper dimensions. On the upper part of this frame a swinging-or oscillating beater-frame, 13, is placed. This frame is constructed as follows: A transverse shaft, a, has its journals I) fitted The A, and it has four arms, at, projecting from it, two near each end and one at right angles to the other. The arms d, therefore,are arranged in pairsthat is to say, there are two, one at each end of the shaft in the same plane, and the plane of one pair is at right angles to that of the other. The two pairs of arms (1 are connected near their outer ends by swords or beaters 0 c, and to the shaft a there are attached two pairs of shorter arms, j", which are in the same planes with the arms d, and are connected by swords or boaters g g r The swords or boaters 9, it will be seen, are considerably shorter than c, and occupy positions in line with the centers of the swords c, as will be clearly seen by referring to Fig. 2.

On the frame A there are secured stationary swords h The swords h correspond in length with the swords e c of the frame B, and'there are three such placed at .each end of the frame A, and in such position that the boaters e e of theframe B may pass between them as said frame is floscillated. (See Fig. 1.) The swords 0; correspond with the swords f, and are so placed that the swordsf may pass between them. The swords 0 a of the oscillating frame 1-3, as 'well as the stationary swords h of the frame A, are distended near their ends, as shown clearlyin Fig. 2, so as to have a greater space between them. The central portions are parallel with each other and considerably closer together. The long swords h of the frame A are stayed by bars a, which hold the shorter swords 7:; but the long swords c of the oscillating frame 13 are not stayed or supported in any way between the arms d.

Tothe under side of the shaft to, at about its center, a lever, j, is attached, and this lever is connected at each end by a link, In, with the ends of a lever, Z, attached to and projecting at equal distances from opposite sides of a rock-'shaft, G. The shaft 0 has an arm, m, attached to one end of it, and this arm is connected by a rod, n, with a crank, 0, attached to a power or driving shaft,D, the crank 0 having aposition on its shaft at right angles with that ofthe arm in on its shaft, as shown clearly in Fig. 11.

The operation of the machine is as follows: A rotary motion is given the shaft D by any proper means, and an oscillating movement is communicated to the frame B through the medium of the levers j, links it It, arml, connecting-rod a, and crank o. The frame B oscillates onequartcr of a revolution; so that its. swords e g of the two pairs of arms at will pass between the stationary swords h z, the swords of one pair of arms first descending at one side of the frame, and then the swords of the other pair of arms descending at the opposite side. Two attendants stand at each end of the machine and first lay the hemp across the outer on distended portions of the swords 71 ,where it is coarsely bruised or broken by the action of the swords c c, the hemp being gradually moved to the central parts of the swords h, where it is also acted upon by the swords y, the swords 1 c passing down a certain distance between the swords h The swords c e at their central parts, in consequence of not being stayed between the arms (Z d, yield or give to a certain extent as they pass down between the swords h, and actwith a drawing or scraping motion on the hemp, separating the dust and woody portion from the fiber. The swords 9i 0 h complete the process, the hemp, as before stated, being moved from the ends of the swords h to their centers. The work is done very expeditiously and in a perfect manner.

A semicircular rod, A", is attached to the upper part of the frame A, to prevent injury to the attendants in case either of the swords of the frame B should fly off during its operation.

I do not claim, broadly, the employment or use of beaters or swords working between each other, irrespective of the construction or arrangement as herein shown, for heaters and swords have been arranged and operated in various Ways; but, I

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- The particular manner of operating the beater-frame Bto wit, by means of the lever links 70 7c, lever Z, shaft G, arm m, c0nnectingrod 12, and crank o-substantia11y as described.
